Description

Technical Field

[0001] This utility model relates to the field of fire sprinkler technology, specifically to a fusible element of a fire sprinkler head made of fusible alloy. Background Technology

[0002] Fire sprinklers are used in fire sprinkler systems. In the event of a fire, water is sprayed out through the sprinkler head's deflector to extinguish the flames. They are categorized into pendant sprinklers, upright sprinklers, standard sprinklers, and sidewall sprinklers. Fire sprinklers are installed on walls or ceilings and connected to a pressurized water network, or individual sprinklers are installed along pipes to protect the area below. When a fire occurs, the fusible metal in the sprinkler head reaches a high temperature and begins to melt, causing water to flow out and extinguish the fire. The sprinkler continuously sprays water above the flames, which in most cases completely extinguishes the fire or at least controls the heat and limits the production of toxic fumes until the fire department arrives.

[0003] However, in the existing technology, after the fusible metal in the fire sprinkler melts, the gasket that supports the fusible metal will spring open. The force of the gasket is uneven when it springs open, causing the gasket to fly in different directions. When the gasket separates, it is easy to get stuck in the frame of the fire sprinkler, affecting the flow of water to the sprinkler. Utility Model Content

[0004] The purpose of this utility model is to provide a fusible element for a fire-fighting fusible alloy sprinkler head, which has the advantage of uniformly opening direction after the fusible metal melts and prevents the mother gasket 101 and daughter gasket 102 from opening in different directions and getting stuck in the fire sprinkler head frame, thus affecting the water flow. This solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fusible element for a fire-fighting fusible alloy nozzle, characterized in that: it includes a fusible component and a splicing component, wherein the fusible component is used to support and block the water outlet, and the splicing component is disposed on the fusible component for limiting and splicing the fusible component.

[0006] Furthermore, the fusible assembly includes a mother gasket, a daughter gasket, a bevel, two mounting ports, and two outlet holes. The daughter gasket is attached to one outer wall of the mother gasket. The bevels are evenly distributed in pairs on the mother gasket and the daughter gasket. The two mounting ports are respectively opened on one outer wall of the mother gasket and the daughter gasket. The two outlet holes are both opened on one outer wall of the mother gasket.

[0007] Furthermore, the mother gasket and the daughter gasket are staggered and bonded together in an octagonal shape, and the outer walls on both sides of the daughter gasket are serrated.

[0008] Furthermore, the assembly includes two insertion components and two limiting components. The two insertion components are both disposed on the female gasket, and the two limiting components are respectively disposed on the two insertion components. The insertion component includes a guide plate, a baffle, and a rectangular plate. The guide plate is fixedly installed on one outer wall of the female gasket, the baffle is fixedly installed on one outer wall of the female gasket, and the rectangular plate is fixedly installed on one outer wall of the guide plate and the baffle.

[0009] Furthermore, the guide plate has an L-shaped cross-section, and the baffle is bent.

[0010] Furthermore, the limiting assembly includes two support plates, a conical plate, a round rod, two torsion springs, a fixed plate, four U-shaped plates, four sliders, and two limiting plates. The two support plates are fixedly installed on one outer wall of the rectangular plate. The conical plate is positioned between the two support plates. The round rod is fixedly installed on the conical plate and rotatably connected to the two support plates. The two torsion springs are fixedly installed on the outer wall of the conical plate, with their ends, which are far apart, fixedly connected to one outer wall of each of the two support plates. The fixed plate is positioned around the conical plate. The four U-shaped plates are fixedly installed on one outer wall of the rectangular plate. The four sliders are slidably installed on the four U-shaped plates. The two limiting plates are fixedly installed on the four sliders, and both limiting plates are fixedly connected to one outer wall of the fixed plate.

[0011] Furthermore, a rectangular opening is provided on one outer wall of the rectangular plate, and the rectangular opening is adapted to the conical plate.

[0012] In summary, due to the adoption of the above-mentioned technologies, the beneficial effects of this utility model are:

[0013] This invention utilizes a fusible component. When the fire sprinkler head is exposed to high temperatures, the fusible metal inside melts. The molten metal drips downwards and accumulates on the main gasket. The accumulated fusible metal then flows into the outlet hole and seeps into the gap between the main and secondary gaskets. Because the molten fusible metal is quite viscous, it effectively bonds and reinforces the main and secondary gaskets. When the fusible metal breaks and water sprays from the pipe connected to the fire sprinkler head, the fire sprinkler head springs the main and secondary gaskets apart. Since the main and secondary gaskets are bonded together, they spring out in the same direction after the fusible metal breaks, preventing them from getting stuck in the fire sprinkler head frame and affecting water flow.

[0014] This invention, through the setting of a splicing assembly, allows the sub-shield to be picked up and aligned with the guide plate. The sub-shield is then pushed to move, moving into the guide plate and fitting against the baffle. Because the outer wall of the sub-shield is serrated, it rubs against the conical plate during movement. This rubbing causes the conical plate to reciprocate and flip, driving the round rod to rotate. The flipping of the conical plate twists the torsion spring, causing it to deform and accumulate elastic force. When the sub-shield stops moving, it also stops rubbing against the conical plate. At this point, the fixing plate is pushed, causing the limiting plate to move. The limiting plate then moves the slider, which slides within the U-shaped plate. The limiting plate restricts and blocks the flipping direction of the conical plate, causing it to lock into the serrated gaps of the sub-shield, thus locking the sub-shield and the mother gasket together. This design offers the advantages of fitting and locking the mother and sub-shields together. Attached Figure Description

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0023] This utility model provides, for example Figures 1-6 As shown, a fusible element of a fire-fighting fusible alloy nozzle includes a fusible component 1 and a splicing component 2. The fusible component 1 is used to support and block the water outlet, and the splicing component 2 is disposed on the fusible component 1 to limit and splice the fusible component 1.

[0024] In addition, the fusible assembly 1 includes a mother gasket 101, a daughter gasket 102, inclined plates 103, two mounting ports 104, and two outflow holes 105. The daughter gasket 102 is attached to one outer wall of the mother gasket 101. The inclined plates 103 are evenly distributed in pairs on the mother gasket 101 and the daughter gasket 102. The two mounting ports 104 are respectively opened on one outer wall of the mother gasket 101 and the daughter gasket 102. The two outflow holes 105 are both opened on one outer wall of the mother gasket 101. More specifically, when the fire sprinkler is subjected to high temperature, the fusible metal inside the fire sprinkler begins to melt. The molten fusible metal drips downward and accumulates on the mother gasket 101. On the 1st, fusible metal accumulates on the mother gasket 101 and flows into the outlet hole 105. The fusible metal enters the outlet hole 105 and seeps into the gap between the mother gasket 101 and the daughter gasket 102. Since the fusible metal is relatively viscous after melting, it can bond and reinforce the mother gasket 101 and the daughter gasket 102. When the fusible metal melts and the water pipe connected to the fire sprinkler sprays water, the fire sprinkler will pop the mother gasket 101 and the daughter gasket 102 apart. Since the mother gasket 101 and the daughter gasket 102 are bonded together, they have the advantage that the direction of the popping apart after the fusible metal melts is the same, which prevents the mother gasket 101 and the daughter gasket 102 from being stuck in the fire sprinkler frame due to different directions after popping apart, thus affecting the water flow.

[0025] In addition, the mother gasket 101 and the daughter gasket 102 are staggered and bonded together in an octagonal shape, and the outer walls on both sides of the daughter gasket 102 are serrated.

[0026] like Figure 1 As shown, the assembly 2 includes two insertion components and two limiting components. Both insertion components are mounted on the female gasket 101, and the two limiting components are respectively mounted on the two insertion components. Each insertion component includes a guide plate 201, a baffle 202, and a rectangular plate 203. The guide plate 201 is fixedly mounted on one outer wall of the female gasket 101, the baffle 202 is fixedly mounted on one outer wall of the female gasket 101, and the rectangular plate 203 is fixedly mounted on one outer wall of both the guide plate 201 and the baffle 202. More specifically, when the sub-gasket 102 is picked up and aligned with the guide plate 201, the sub-gasket 102 is pushed to move. The sub-gasket 102 moves into the guide plate 201 and fits against the baffle 202. Because the outer wall of the sub-gasket 102 is serrated, the sub-gasket 102 moves towards the conical shape during movement. The plate 205 is rubbed, and the conical plate 205 is rubbed and flipped back and forth. The conical plate 205 drives the round rod 206 to rotate. When the conical plate 205 flips, it twists the torsion spring 207. The torsion spring 207 is twisted and deformed and accumulates elastic force. When the sub-waist 102 stops moving, the rubbing of the conical plate 205 also stops. At this time, the fixed plate 208 is pushed, and the fixed plate 208 drives the limiting plate 211 to move. The limiting plate 211 drives the slider 210 to move. The slider 210 slides in the U-shaped plate 209. The limiting plate 211 limits and blocks the flipping direction of the conical plate 205, so that the conical plate 205 is stuck in the serrated gap of the sub-waist 102, locking the sub-waist 102 and the mother pad 101 together. It has the advantages of fitting the mother pad 101 and the sub-waist 102 together and limiting and locking them.

[0027] In addition, the guide plate 201 has an L-shaped cross section, and the baffle 202 is bent.

[0028] Additionally, the limiting assembly includes two support plates 204, a conical plate 205, a round rod 206, two torsion springs 207, a fixing plate 208, four U-shaped plates 209, four sliders 210, and two limiting plates 211. The two support plates 204 are fixedly installed on one outer wall of the rectangular plate 203. The conical plate 205 is disposed between the two support plates 204. The round rod 206 is fixedly installed on the conical plate 205 and rotatably connected to the two support plates 204. The two torsion springs 207 are fixedly installed... The two torsion springs 207 are mounted on the outer wall of the conical plate 205. The ends of the two torsion springs 207 that are far apart from each other are fixedly connected to the outer wall of one side of the two support plates 204. The fixing plate 208 is set on the periphery of the conical plate 205. The four spiral plates 209 are all fixedly mounted on the outer wall of one side of the rectangular plate 203. The four sliders 210 are slidably mounted on the four spiral plates 209 respectively. The two limiting plates 211 are fixedly mounted on the four sliders 210 respectively. The two limiting plates 211 are all fixedly connected to the outer wall of one side of the fixing plate 208.

[0029] In some embodiments, a rectangular opening is provided on one outer wall of the rectangular plate 203, and the rectangular opening is adapted to the tapered plate 205.

[0030] Working principle:

[0031] Step 1: Assemble the parts. Pick up the sub-shield 102 and align it with the guide plate 201. Push the sub-shield 102 to move it. The sub-shield 102 moves into the guide plate 201 and fits against the baffle 202. Because the outer wall of the sub-shield 102 is serrated, it rubs against the conical plate 205 during movement. The conical plate 205 is rubbed and flips back and forth. The conical plate 205 drives the round rod 206 to rotate. When the conical plate 205 flips, it twists the torsion spring 207. The torsion spring 207 is torsion-induced. The rotation generates deformation and accumulates elasticity. When the sub-waist 102 stops moving, the rubbing of the conical plate 205 also stops. At this time, the fixed plate 208 is pushed, and the fixed plate 208 drives the limiting plate 211 to move. The limiting plate 211 drives the slider 210 to move. The slider 210 slides in the loop plate 209. The limiting plate 211 limits and blocks the flipping direction of the conical plate 205, so that the conical plate 205 is stuck in the serrated gap of the sub-waist 102, locking the sub-waist 102 and the mother wedge 101 together.

[0032] Step Two: Welding and Spin-Off. When the fire sprinkler head is subjected to high temperature, the fusible metal inside the fire sprinkler head begins to melt. The molten fusible metal drips down and accumulates on the mother gasket 101. The fusible metal accumulates on the mother gasket 101 and flows into the outlet hole 105. The fusible metal enters the outlet hole 105 and seeps into the gap between the mother gasket 101 and the daughter gasket 102. Because the fusible metal is relatively viscous after melting, it adhesively reinforces the mother gasket 101 and the daughter gasket 102. When the fusible metal melts and water sprays from the water pipe connected to the fire sprinkler head, the fire sprinkler head will pop the mother gasket 101 and the daughter gasket 102 apart. Because the mother gasket 101 and the daughter gasket 102 are adhered, the popping direction is uniform, preventing the mother gasket 101 and the daughter gasket 102 from being stuck in the fire sprinkler head frame and affecting the water flow.
